Ohio Gov. John Kasich is having lunch with Mitt Romney on Thursday, becoming the third Republican presidential candidate to privately meet with the 2012 GOP nominee this month. Kasich, who announced his presidential run on Wednesday, is in the midst of his announcement tour in New Hampshire, where Romney has a vacation home. Kasich spokesman Chris Schrimpf said Romney invited the governor after learning he would be campaigning nearby. Earlier this month New Jersey Gov. Chris Christie and Florida Sen. Marco Rubio visited Romney's vacation home over the Fourth of July holiday weekend. Romney has not said whether he plans to endorse a candidate in the race.
